Is polyphemus a villain

I'm sure he was just misunderstood. He loved Galateia and tried to woo her with a song, but she spurned his advances. That had to be crushing, emotionally speaking, for a cannibalistic Cyclopes and it's little wonder he acted out by crushing Acis when he discovered the god with his sea-nymph. He only ate some of Odysseus' men, and c'mon, he was hungry, but was it really necessary for Odysseus to ply him with wine and pierce his eye with a burning stake as he slept? I'd throw rocks too if I woke up with a blinding hangover...
